Walmart assured the media that the site was not hacked.
"We experienced a technical error that caused some items to show incorrect pricing," Walmart said in a statement on Wednesday morning. "We are working quickly to correct the error and during this time, there may be intermittent site availability. We apologize for any inconvenience to our customers."
Just two weeks ago, Walmart stores in Louisiana experienced another frenzied shopping day, but that time with live customers. An error in the food stamps EBT system caused account limits to temporarily disappear, leading customers to load up shopping carts with hundreds of dollars worth of items.
